Built with an extruded aluminum frame and blades, it operates on a power-closed, spring-open actuation cycle. The damper accepts 24-volt AC, 60 Hz power, produces 71 inch-ounce of motor torque, and cycles through a 30-second power-open and 10-second spring-return sequence. Leakage is rated at less than 1 percent at 0.5 inch WC, and maximum static pressure rating is 1 inch WC. A mechanical visual position indicator is included for quick field verification of blade status.\u003c\/p\u003e\u003cp\u003eThis damper is sized for an 8-inch by 26-inch duct opening and is used in residential applications where zone-by-zone airflow control is required. It integrates with TrueZone electronic zoning panels and other compatible electronic zoning systems. The bottom-mount motor configuration suits standard rectangular duct installations, and LED indication is included to assist during commissioning and troubleshooting. Typical applications include split-system and air-handler-based forced-air systems serving multiple zones.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRectangular parallel-blade design with extruded aluminum frame and blades\u003c\/li\u003e\n\u003cli\u003ePower-closed, spring-open actuation for fail-safe duct opening on power loss\u003c\/li\u003e\n\u003cli\u003e24-volt AC, 60 Hz motor with 71 inch-ounce torque rating\u003c\/li\u003e\n\u003cli\u003eLess than 1 percent leakage at 0.5 inch WC for tight shutoff performance\u003c\/li\u003e\n\u003cli\u003eMechanical visual position indicator and LED indication included\u003c\/li\u003e\n\u003cli\u003eCompatible with TrueZone and other electronic zoning control systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with TrueZone and other electronic zoning systems in residential forced-air HVAC applications.
